Title: Process for the prenatal diagnosis of genetic abnormalities
Inventor: AHLERT DOROTHEE
IPC: G01N33/577
Filed: 1993-05-11
Abstract: ABSTRACT                PROCESS FOR THE PRENATAL DIAGNOSIS      OF GENETIC ABNORMALITIES         It has been possible to demonstrate clearly both in umbilical  cord  blood  samples  and  after  the  separation  of pregnancy blood that the combination of the triple gradient and MACS with anti-CD71 marked cells is a very effective method of enriching nucleated erythrocytes.  The proportion of nucleated erythrocytes in the umbilical cord blood was between 72 and 89% after both enrichment methods.  It has been possible to detect nucleated erythrocytes in the positive fraction according to the triple gradient and MACS in all cases  in pregnant women at various  gestation stages.   The  variation  in  the  number of enriched nucleated  erythrocytes  in various  pregnancies  very probably reflects individual differences in the foeto-maternal cell ratio at various stages in pregnancy.  The process described here makes it possible in normal male blood and that of non-pregnant women  to demonstrate no nucleated erythrocytes,  by contrast with pregnant women at various stages of gestation.  The method is also highly reproducible and suitable for clinical diagnosis.  With fluorescence in situ hybridisation it has been possible  to  detect  a  foetal  trisomia  in  all  three  cases investigated.  The enrichment of nucleated erythrocytes is thus strong enough to diagnose infantile aneuploids using fluorescence in situ hybridisation.   It is  therefore obvious that  it  is possible with this only slightly invasive and relatively simple and economical method to conduct screening examinations for three of the most important trisomias (13, 18 and 21) and monogenic diseases (with the aid of the PCR) with virtually no risk to the patient and the child.

Abstract: The phase transformation temperature of a metal silicide layer formed overlying a silicon layer on a semiconductor wafer is lowered.      First, a refractory metal is disposed proximate to the surface of the silicon layer, a precursory metal is deposited in a layer overlying the refractory metal, and the wafer is heated to a temperature sufficient to form the metal silicide from the precursory metal. The precursory metal may be a refractory metal, and is preferably titanium, tungsten, or cobalt. The concentration of the refractory metal at the surface of the silicon layer is preferably less than about 101 atoms/cm3. The refractory metal may be Mo, Co, W, Ta, Nb, Ru, or Cr, and more preferably is Mo or Co. The heating step used to form the silicide is performed at a temperature less than about 700°C, and more preferably between about 600-700°C. Optionally, the wafer is annealed following the step of disposing the refractory metal and prior to the step of depositing the precursory metal layer. Preferably, this annealing step is performed at a wafer temperature of at least about 900°C.

Patent CA-2122857-A1 (CA)
Inventor: SAUSNER ANDREAS
IPC: F16K31/06
Filed: 1994-05-04
Abstract: An electromagnetically operable valve includes a housing, an annular magnetic coil positioned therein and a plunger of metallic material which is surrounded by the coil and reciprocatible in axial direction of the coil to and from a valve seat of the valve.  A sealing body of elastomeric material for the sealing of the valve seat is mounted to a first end of the plunger adjacent the valve seat.  The plunger and the sealing body are form fittingly interconnected to achieve a mechanical connection which obviates the use of an adhesion promoter between the metallic and elastomeric materials.  This leads to a simplified manufacture and reduced manufacturing costs.

Title: Forearm lifter
Inventor: GAMMER PETER
IPC: A61F2/58
Filed: 1994-06-07
Abstract: A forearm lifter for assisting in the articulation of a mating forearm part of an arm prosthesis with respect to a mating upper arm part about at least one elbow axis is disclosed. The forearm lifter includes: (i) a spring element; (ii) a mechanism having an input and an output, with the spring element directly or indirectly applying a tensile force to the input of the mechanism; and (iii) a tension element having one end acted upon by the output of the mechanism, and having another end which can be fastened at a fixed point on said mating upper arm part. The fixed point and the elbow axis define a torque lever, such that the force that is transmitted through the mechanism from the spring element applies torque to the mating upper arm part in such a manner that the curve of the torque acting at the fixed point, plotted against the angle of articulation of said forearm part, is approximately parabolic. The torque has its minimum values in both the forearm extended position and at maximum forearm bending. The torque has its maximum value when said upper arm mating part and said forearm are at approximately 90°.

Patent CA-2152968-A1 (CA)
Title: Electrolysis cell diaphragm reclamation
Inventor: ARNOLD MARK L
IPC: C25B11/00
Filed: 1995-06-29
Abstract: There is now disclosed a method of restoring a used article utilized in electrolysis, such as in a chlor-alkali cell. The used article is usually the cell diaphragm, but may be a cell electrode, particularly when it is in assembly with the cell diaphragm.  The restoration method involves treating the article, typically in place in the cell, but which may be removed from the cell by soaking in a treating composition containing most always hydrochloric acid and corrosion inhibitor.  The article after treatment may be baked at elevated temperature.  When baking is utilized it can come before soaking.  With or without baking, the article may or may not be involved in a wetting step.  Where the restoration involves an article utilized in a chlor-alkali cell, the restoration can readily reduce the problem of hydrogen in the chlorine product produced.   Such treatment can also lead to reduced cell voltage as well as reduced cell anolyte level.

Title: Tail piece for the forked boom of a rig for surfboards
Inventor: NAMUR MARC
IPC: B63H8/52
Filed: 1995-08-23
Abstract: The forked boom tailpiece (4) consists of a tube bend segment (9) made of synthetic material that is elastic to a certain extent, which is inwardly open, is pushed open on an aluminum tube bend (10) for fastening the extension bars (3) of the forked boom by means of a spring-loaded latch (11), and is fastened to the tube bend (10). On the upper side of the tube bend segment (9) is a flat pin (12) with a wide straight-through slit (13) for taking up the clew (8) of the sail (7) formed with an inserted fastening ring (14). On the outside of the pin there is a mounting opening (15) for the installation of a spring-loaded latch (16) with a spring-urged swivelling hook (17). The swivelling hook (17) projects outwardly with its hook-shaped actuating end (19) through the mounting opening (15) of the take-up pin (12) of the tube bend segment (9). The swivelling hook (17) is positioned so it can turn on a compression rivet (19) for fastening the tube bend segment (9) to the tube bend (10) for connecting the extension bars (3). When opening the spring-loaded latch (16) the hook (17) swivels out of the clew ring (14) of the sail (7) in the direction of arrow a, and at the same time the locking spring (21) operating on the swivelling hook (17) is pulled tight.          To close the spring-loaded latch (16) a light touch of the finger on the actuating end (18) of the swivelling hook (17) suffices to snap it in, caused by the spring resistance of the locking spring (21) in the direction of arrow b in the clew ring (14) of the sail. The forked boom tailpiece (4) makes possible a safe, quick, backlash-free fastening of the sail clew by means of a spring-loaded latch (11), and offers, furthermore, the opportunity to fasten and trim the sail in the traditional way with a rope's end.
